MAX10 OSC2 IO timing

MAX 10 02SC 上电期间所有IO上有一个4ms的脉冲输出,怎么解决。

 

Hi,

我这边使用10M02SC设计,其中:

DEV_OE 悬空

NCONFIG ​ GND

CONFIG_SEL GND

每次上电,我发现所有IO都会有一个约4ms的脉冲信号输出,我试过去除掉片内代码,配置过unused io状态,in-system-program时的IO状态​

​全部都无法改善。

请问这里有什么解决办法。

以上感谢各位。​

Hi Bryan,

你好,是的。当power up 时,​所有的i/O pin 会pull up。然后恢复原状
